Technical Abstract

The invention provides a method of determining a comparative expression profile in an individual by comparing the expression levels of a sample of molecules in a population of molecules in a specimen from the individual with a health-associated reference expression region of the sample of molecules, wherein expression levels within the health-associated reference expression region indicate a reference expression profile and wherein expression levels outside the health-associated reference expression region indicate a perturbed expression profile. The invention also provides methods of diagnosing a disease or a health state in an individual by comparing the expression level of a sample of molecules in a specimen from the individual with a health-associated reference expression region of the sample of molecules. The invention additionally provides a method of classifying a population by drug responsiveness.

Legal claims defining the scope of protection, as filed with the USPTO.

1

1. A computational method of classifying a population by drug responsiveness, comprising: (a) creating a multidimensional space of n dimensions, wherein n represents the number of different molecules being analyzed in a specimen from each individual in a population of individuals administered a drug and wherein said multidimensional space contains n axes, each of said axes relating to the expression level of a molecule of said n molecules, wherein n is 3 or more molecules and wherein said molecules are nucleic acids or polypeptides; (b) determining multidimensional coordinate points for each individual in said population, wherein each of said multidimensional coordinate points is representative of the expression levels of said n molecules in each of said individuals; (c) determining a drug response-associated reference expression region of a group of individuals in said population using said multidimensional coordinate points, thereby classifying said group of individuals into a drug response reference population; and (d) providing an output of said classification of said drug response reference population to a user.

2

2. The method of claim 1 , further comprising the step of correlating said group of individuals with a response to said drug.

3

3. The method of claim 2 , wherein said response is alleviation of a sign or symptom associated with a condition of an individual administered said drug.

4

4. The method of claim 1 , wherein the expression levels of said molecules are determined by contacting said specimen with a target.

5

5. The method of claim 4 , wherein said target is an array.

6

6. The method of claim 4 , wherein said target comprises nucleic acid ligands.

7

7. The method of claim 4 , wherein said target comprises antibody ligands.

8

8. The method of claim 1 , wherein said specimen is selected from the group consisting of leukocytes, blood, and serum.

9

9. The method of claim 1 , wherein said molecules in said specimen comprise nucleic acids.

10

10. The method of claim 1 , wherein said molecules in said specimen comprise polypeptides.

11

11. The method of claim 1 , wherein n is 5 or more molecules.

12

12. The method of claim 1 , wherein n is 10 or more molecules.

13

13. The method of claim 1 , wherein n is 20 or more molecules.

14

14. The method of claim 1 , wherein n is 50 or more molecules.

15

15. The method of claim 1 , wherein n is 100 or more molecules.

16

16. The method of claim 1 , wherein n is 200 or more molecules.

17

17. The method of claim 1 , wherein n is 500 or more molecules.

18

18. The method of claim 1 , wherein n is 1000 or more molecules.

19

19. A computational method of classifying a population by drug responsiveness, comprising: (a) creating a multidimensional space of n dimensions, wherein n represents the number of different molecules being analyzed in a specimen comprising leukocytes from each individual in a population of individuals administered a drug and wherein said multidimensional space contains n axes, each of said axes relating to the expression level of a molecule of said n molecules,wherein n is 3 or more molecules and wherein said molecules are nucleic acids or polypeptides; (b) determining multidimensional coordinate points for each individual in said population, wherein each of said multidimensional coordinate points is representative of the expression levels of said n molecules in each of said individuals; (c) determining a drug response-associated reference expression region of a group of individuals in said population using said multidimensional coordinate points, thereby classifying said group of individuals into a drug response reference population; and d) providing an output of said classification of said drug response reference population to a user.

20

20. The method of claim 19 , further comprising the step of correlating said group of individuals with a response to said drug.

21

21. The method of claim 20 , wherein said response is alleviation of a sign or symptom associated with a condition of an individual administered said drug.

22

22. The method of claim 19 , wherein the expression levels of said molecules are determined by contacting said specimen with a target.

23

23. The method of claim 22 , wherein said target is an array.

24

24. The method of claim 22 , wherein said target comprises nucleic acid ligands.

25

25. The method of claim 22 , wherein said target comprises antibody ligands.

26

26. The method of claim 19 , wherein said molecules in said specimen comprise nucleic acids.

27

27. The method of claim 19 , wherein said molecules in said specimen comprise polypeptides.

28

28. The method of claim 19 , wherein n is 5 or more molecules.

29

29. The method of claim 19 , wherein n is 10 or more molecules.

30

30. The method of claim 19 , wherein n is 20 or more molecules.

31

31. The method of claim 19 , wherein n is 50 or more molecules.

32

32. The method of claim 19 , wherein n is 100 or more molecules.

33

33. The method of claim 19 , wherein n is 200 or more molecules.

34

34. The method of claim 19 , wherein n is 500 or more molecules.

35

35. The method of claim 19 , wherein n is 1000 or more molecules.
